When I listened to Apocalyptica’s first album when I was in high school, I was impressed. I’d listened to classical re-arrangements of rock music in the past – my parents own “The Baroque Beatles Book” – but I’d never been impressed by them. It always felt like they (whoever did the arrangement) mapped the various notes 1-for-1 with other parts from the original performance (with either brass or violins for vocals). Apocalyptica, on the other hand, felt like more of a clear re-interpretation.
